M54HCT244：Rad-Hard Octal Bus Buffer 3-State
The M54HCxxx and M54HCTxxx series are composed of 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. They include a large set of gates, flip-flops, multiplexers, counters, bus interface and several other functions. The radiation hardness, the single event latch-up (SEL) immunity and the housing in hermetic packages of all types of both series make them ideally suited for use in the most difficult environmental conditions.
Key Features
- 2 to 6 V operating voltage
- Low power DC dissipation: 1 μA max. at 25 °C
- High speed tPD
= 8 ns typ. at 25 °C
- Symmetrical outputs characteristics
- High noise immunity: 28 % of min. VCC
- Hermetic packages
